The purpose of this research is to clarify how human tacit (or intuitive) knowledge can combine with computer explicit (or logical) knowkedge, thereby an organization consisted of humans and computers can be more intelligent.An interaction model between human tacit knowledge and computer explicit knowledge was built based on surveys of research activities of scientists and engineers in research centers of Japanese technology-based companies.According to this model, computer program was developed and tested by scientists and engineers in research centers of Japanese technology-based companies.The interaction model between human and computer was found effective. Human can convert his viewpoints with guidance of computer, which means that computer explicit knowledge as guidance can stimulate human in intuitively changing his viewpoints which is tacit knowledge.This model is effective as an approach to designing organizational intelligence.Organization
